Claims.

Our invention relates to a package-making machine and has particular reference to a machine for forming a container for confections and similar articles wherein a tubular container member 5 is formed, a bottom inserted therein, a napkin,

or other accessory is inserted in the container, and the finished container with its bottom and accessory is ejected from themachine, ready for the reception of contents to be placed therein.

In the packaging of certain commodities, such as ice cream, a tubular container formed of paper or other thin sheet material is employed, such containers being formed with a tubular body portion into one end of which is inserted a disc of a sheet material to form a bottom, after "which the container is passed to filling machines wherein the ice cream or other contents are inserted and a disc-like cover member is placed thereon. One particular form of such container is illustrated in the United States Letters Patent granted to Charles F. Allen and Selwyn Smith, No. 1,932,169 and dated October 24, 1933, wherein the tubular container is formed of a pair of strips of paper or similar material wound helically, the inner strip being wound with the edges of adjacent coils in abutting relation to each other and the outer strip being wound in overlapping relation to the junction adjacent the coils of the inner strip, such tube being cut to a desired length and a disc-like or cup-like bottom member being pressed inwardly from one end to form the bottom thereof, a similar disc or cup-like member being.

employed to close the top of the container after it has been filled. This container may be employed for ice cream or similar frozen confec-- tions by merely filling the tubular container with ice cream, water ices, sherbets, or other products, while the product is in a semiliquid or flowable 40 condition, after which the container with its contents may be placed in a hardening room to harden and be preserved until ready for consumption. 3

' When such tube is employed for containing ice cream and similar products the lower portion of bottom of the'container and this hollow'spacemay be employed for the reception of a paper napkin or some other accessory assisting in'the handling of the confection.

It is an object of our invention, therefore, toprovide a machine which will manufacturesuchtubular container in commercial quantities at relatively low cost. 4

Another object of our invention is to provide a machine for manufacturing tubular containers of the character set forth, wherein paper strips 5 are fed from a substantially continuous source of supply to a stationary mandrel and about which said strips are wound, one of said strips being wound directly in contact with the mandrel, with the, adjacent coils thereof abutting each other and with the other strip wo nd about the coiled v first strip, the center line of t e second strip being arranged at approximately the junction between adjacent coils of the inner strip.

Another object of our invention is toprovid'e a machine of the character set forth in the preceding paragraph, wherein the paper strips are continuously wound upon each other to form a substantially continuous length of tube and in which mechanism coordinated with the winding of the paper strips is employed to out such tube into appropriate lengths as it is wound.

Another object of our invention is to provide a machine of the character set forth, wherein the sections of tube cut to length are delivered to a bottoming mechanism wherein a cuplike bottom is formed and is pressed into desired positional relation within .the cut section of tube.

Another object of the invention is to provide a machine of the character set forth in the preceding paragraphs, wherein an adhesive is applied to the cuplike bottom member and to the interior walls of the tube as the bottom is in-- serted therein to constitute an adhesive, .holding the bottom in its desired positional relation.

Another object of the invention is to provide a machine of the character set forth in the preceding paragraphs, wherein the waxing device is controlled by the mechanism which inserts the bottom to cause the spraying of wax from the spraying deviceonly when said spraying device is passing through a predetermined area within the tube.

Another object of the invention is .to'provide a machine as set forth, wherein, in a single continuous operation a bottom disc is cut from a continuous supply of paper, is formed into a cuplike bottom member and is inserted into the cut section of tube to the desired positional relation. Another object of the invention is to provide a napkin folding mechanism which will draw a. supply of napkin stock from a substantially continuous supply thereof, automatically fold. said napkin stock into a folded condition, and then automatically out said folded napkin stock into the desired length and insert said out lengths into the space formed between the bottom 'and' the lower end of the cut section of tube. v r

. Another object of the invention is to provide a mechanism as set forth in the preceding para graph, wherein the cut length 'of napkin stock U is subsequently refolded into a relatively com pact member capable of being inserted into a small diameter container tube.

All of the mechanisms A, B, C, D and E are illustrated as being supported upon a face plate 2, near the front of the machine, such face plate being preferably formed as indicated particularly in Fig. l with a bifurcated lower end forming apair 'of legs 3 and 4 adapted to rest upon'base rails 5 and 6, respectively. The base rails 5 and 6 extend rearwardly' from the face plate 2, and the face plate is braced'thereon by a pair of braces 'I and 8. Erected upon the rails 5 and E is a framework consisting of an upright 9 extending upwardly from the rail 5 and having its upper end connected by a horizontal bar II! to the rear surface of the face plate 2, while a similar vertical upright H extends upwardly from the rail 6 and has its upper end connected by means of a horizontal bar I2 to the rear face of the face plate 2.

The horizontal bars l0 and I2 are connected by-cross bars l3 and M to each other laterally of the machine, and these cross bars also con-" stitute a shelf for supporting a glue pot and gluing mechanism, indicated generally atv F in Fig. 3. Similarly a wax pot and waxing mechanism, indicated generally at G in Fig. 3, is supported upon and extends laterally across the rails l0 and H. Below the horizontal bars I0 and H a second pair of horizontal bars l5 and I 6 extend between the rear surface of the face plate 2 and the uprights 9 and II, respectively,

. to constitute a shelf upon which the napkin fanning mechanism H may be mounted.

In order to facilitate the more ready understanding of 0111" invention, it is deemed advis- -able to segregate the various portions of the machine A, B, C, 'etc. and to take each of these elements up in detail as a separate section.

Tube winding apparatus Since we have illustrated our invention as being particularly adapted for the manufacture of a tubular container for ice cream or similar confections we will describe the tube winding hereinafter referred to as S--|, is preferably fed 20 against which a winding roller 2| bears to frictionally engage strips of paper therebetween to feed said strips of paper to' the mandrel and to wrap the same around the mandrel and feed the tube so ,formed forwardly along the mandrel. The mandrel 2|] is illustrated as being formed of a cylindrical metallic member, the upper end of which is rigidly and stationarily secured in a bore 22 (see Fig. 4) in a mandrel supporting bracket 23 which is in turn mounted upon the front face of the face place 2.

It will be observed that the mandrel 20 is supported only at its upper end, and has a considerable length preferably in excess of the length of one of the finished container tubes.

The winding roller 2| is rigidly secured to a shaft 24, which is disposed at an angle to the longitudinal axis of the mandrel 2|! and preferably immediately at the rear of the mandrel 20. The shaft 24 is rotatably mounted in a roller bracket 25 pivoted at 26 to a mounting bracket 21. The mounting bracket 21 is secured to the front face of the face plate 2 upon a pivot pin 28 and from an inspection of Fig. 1 it will be observed that the pivot pin 28 is disposed immediately at the rear of the mandrel 20 and in a vertical plane drawn through the axis of the mandrel 20. It will also be observed that the pivot pin 28 constitutes a pivotal support for the mounting bracket 21 at the intersection between a plane passing through the axis of rotation of the shaft 24 and the said vertical plane passing through the longitudinal axis of the mandrel 2|I.

Theface plate 2 is provided with an outstanding lug 29 through which extends an adjusting screw 30 threadedly engaging the'mounting bracket 21 near the outer end thereof so that by turning the adjusting screw 30 the mounting bracket 21 may be moved about its pivot 28 to change the angu ar relation between the ax s of rotation of the shaft 24 and the longitudinal axis of the mandrel 20. This adjustment of the mounting bracket 21 changing the angulardisposition of the roller 2|, winds the strips of different widths upon the mandrel 20 and yet maintains the adjusting coils of the strips so wound in abutting relation with each other. 4

By referring particularly to Fig. 2, it will be observed that the frame of the machine at the rear of the face p ate constitutes a support for a pair of reels 3| and 32, of which reel 3| indi-. cates a reelof paper material to form the inner layer of the finished tube, while reel 32 indicates the reel, of paper employed to form the outer layer of the container. As was described par-' ticularly in the Allen and Smith patent hereinbefore referred to, the paper employed to form the inner layer of the tube is considerably heavier than that employed to form the outer layer of the tube so that after the tube has been wound up it may be torn down by unwindingthe coils constituting the inner layer of the container and the abutting edge of such strip of material will constitute substantial cutting edges, cleanly severing the strip forming the outer layer of material. The reel 3| is illustrated as being supported upon a 'an upright 33, which extends from the siderail 5 33 by means of a bolt 34 upon which the reel of paper 3| may be slipped and may be held in place thereon by means of a suitable washer 35 a'nda nut 36. The paper strip drawn from the reel 3|,

over a guide roller'3l, rotatably mounted upon the upright 33 and thence passes through a tensioning device 38 and over, the wax coating apparatus G to coat one surface of the strip S with a layer of ,wax for the, double purpojseof making this strip of paper moistureproof when the container is adaptedto receive liquid or substantially liquid contents, and,also for thepurpose of providing a substantial lubrication assisting in the ready winding of this strip and to the feeding of this strip about the mandrel 20.

The waxing apparatus .G will be described in full-hereinafter, but for the purposes of describing it at this point, it sufiicesto say that the strip S'| is drawn across a waxing ro ler 39 which dips into the wax containedwithin a wax pot 4|) so that as the strip passes across this roller a thin coating of wax will be applied to what is then the underneath surface of the strip S|. The strip then passes over a guide plate 4| and thence over a guide channel 42 supported upon a pin 43 mounted in the roller bracket 25. From an inspection of Fig. 1, it will be observed that the channel 42 is directed inwardly and downwardly toward the surface of the mandrel 20 so as to pass the strip S| immediately at the rear of the mandrel 20. This strip S-| may then be wound about the mandrel between the roller 2| and the rear surface of the mandrel 20.50 that as the roller 2| is rotated the strip S| .will be continuously drawn off the reel 3| and continuously wound about the mandrel 20 in a heix with the adjacent edges of adiacent coils of the helix in closely abutting relation with each other.

In order to facilitate the threading of. the str p S- between the roller 2| and the mandrel 2|]. we mount the shaft 24 on the roller bracket 25 and pivot this bracket at 26 so that it has a considerable movement forwardlv and rearwardy relative to the mandrel 20. The amount of this movement may be controlled by a wedge 44 threaded upon a handwheel shaft 45 at the outer end of which is a handwheel 46 so that by turning the handwheel in one direction the wedge 44 is moved in a right-hand direction as shown in Fig. 1-, this wedge 44 bearing u on a in 41 carried by the roller bracket 25. This action will force the rol er bracket 25 toward the mandrel 20 and will bring the roller 2| into close relation with respect to this mandrel. while movement of the handwheel 46 in the opposite direct on will release the pressure of the wedge 44 and permit the rol er 2| to retract from the mandrel. In order to cause the roller 2| to wind the strip S-l about the mandrel 20. we apply motive power to the It will be observed means of a belt 58 to a main drive pulley 5|. The 'main drive pulley 5| is r gidly secured upon a pulley shaft 52 which is rotatably mounted in a bearing. 53a secured to and extending forwardly of the front face of the face pate 2.

The lower end of the pulley shaft 52 is pro vided with an elongated spur'gear 53 which meshes with a gear 54 rigidly secured upon a power shaft 55. The power shaft 55 extends verticallyof the machine. having a plurality of bear rg supports, the upper of which is formed in the supporting bracket 23, the lowermost of which is formed by a bearing bracket 56 secured upon the front face of the face plate 2, while an intermediate bearing bracket 51 engages and mediately below the supporting bracket 23 is a beveled gear 58 which is in turn meshed with a bevel gear 59 rigidly secured to .the roller shaft 24. Thus rotation of the drive shaft 55 by the motor I will apply rotary power to the roller 2|. Due to the angular depression between the roller 2| and the mandrel .20 rotation of the. roller 2| will cause the strip S.l to be drawn from-its reel 3| and to be fed about the mandrel 20 in the form of a helix and as this helixis'formed on the mandrel the entire helix will be fed downwardly along the mandreL In order to insure that the adjacent coils of the strip Sl, .as they are wound about the mandrel, are in closely abutting relation with each other, but not in overlapping relation with each other, the operator of the machine should accurately adjust the angular disposition of the roller by means of the adjusting screw 30 after he has started the winding operation. This may be readily accomplished by observing the uppermost coils of the helix so formed upon the mandrel and adjusting the screw 30 until these adjacent coils are exactly in abutting relation.

By referring again to Fig. 2, it will be observed that the strip of material used to form the outer layer of the container is drawn from the reel 32, and since this strip acts as the binder for" the adjacent coils of the .inner layer formed by the strip S-l, this strip will be hereinafter referred to. as S2, and should have a coating of glue or other adhesive applied to one side thereof prior to its being wound around the mandrel 20. It

will be observed that the strip 8-2 passes directly from the reel 32 over a guide roller 60' which is preferably mounted upon the gluing mechanism F and which will be described in detail hereinafter, but at this point in the descrip-- tion it is suflicient only to note that the gluing mechanism includes a glue applying roller 6! over which the strip S2 passes to receive a thin coating of glue or similar adhesive. From the glue applying'mechanism F the strip S -2 passes over a guide plate 62 on the side edge of.

outer surface of the strip S-.-2. In threading the machine, the operator preferably makes a few turns of the strip 8-2 over the strip S*|, and.

then pastes the end of the strip S-l directly to the strip S2. Then when the motor I is started to mechanically driye the roller 2|, this roller will frictionally engage both of the strip S -l and S2 and feed them helieally around the mandrel, while, at the same time, the winding roller- 2|, the face of which is considerably broad, will press the strips S-l and S2 tightly toward the mandrel and will iron 'out the helices formed by the two strips, causing the outer strip 3-! to be smoothly glued to the inner strip,.and thus forming a self supporting-tube which will be fed I along the length of the mandrel 20.

' With the parts of "the machine thus far described it will be observed that the strips 8-! and S--2 are fed from either reels 3| and" 32, respectively, and are wound about the mandrel 8,181,214 supports the shaft 55 intermediate its ends. Im-

to form an elongated tubular member which may be cut into any desired length to form the finished container.

Since it is desired that the machine shall operate substantially continuously, we prefer to provide auxiliary reels ila and 32a of strip material suitably supported upon the frame of the machine ready to be put into' operation as soon as one of the reels 3 l or 32 becomesrexhausted The reel 3la may be secured. to the upright 33, near the upper end thereof upon a bolt or pin 34a and held in place by means of a washer 35a and a nut 36a. Likewise the reel 32a may be supported upon the rear upright ll upon a similar bolt, washer and nut assembly. Thus when the reel becomes exhausted it is but a simple matter to start the end of the reel 3m, thread the same over a guide roller 31a (disposed immediately above the roller 31) and then the strip S--l is drawn from the reel Ma and may be "threaded to the mandrel in the same manner as herein- 'before described. In like manner when the reel 32becomes exhausted the'strlp Sl may be started from the fresh reel 32d and may be fed from a guide roller 60a and thence to the mandrel in the same manner as was hereinbefore described for the strip 8-2. To prevent the rapid unwinding of the strips Sl and 5-2 from their reels, tensioning members 64 may to bear uponthe reels.

It will be observed that the mandrel 20 has considerable length in excess of the coil required to windthe strips 8-! and 8-2 upon each other and to iron them out so that a substantially great length of tube T is always upon the mandrel 20.

be; employed However, to prevent unnecessary friction between I the longlength of tube T and, the length of the mandrel 20, we prefer to reduce the diameter of the mandrel 20 after it has passed the portions thereof contacted by the aligning roller 2|. This reduced portion is indicated particularly in Fig.

4, at 20a. j

Tube cutting apparatus The strips S-l and 3-2 are now wound in an elongated tube extendingalong the mandrel 20 and may be cut into the desired lengths to form the containers by means of the tube cutting apparatus B. This cutting apparatus is particularly shown in Figs. 1 to 7, inclusive, and

comprises a pair of shearing wheels 10 and II. The diameter of the shearing wheel 10 is preferably substantially the same asthe exterior diameter of the tube'fofming. mandrel 20. That is,

the diameter of the shearing wheel 10 should substantially conform with the interior diameter of the tube T which is formed by the winding of the strips S| and S2 about the mandrel as hereinbefore described.

The shearingwheel 10 is rigidly secured upon the lower end of a shaft I2 which-extends through a bore 13 extending longitudinally through the mandrel 20 and concentrically with the longitudinal axis thereof. The cooperating cutting wheel II is illustrated as being rigidly secured. upon the The bearing bracket 11 is illustrated-as being rigidly secured to the upper end of a rod 8| which passes downwardly through a bearing 82 formed upon the bearing bracket 23, and has its lower end guided in a bearing 83 formed upon the bearing bracket 51 for the drive shaft 55. The

' rod 8| is preferably both rotatably and slidably mounted in its bearings 82 and 83 and is nor- .mally urged toward its uppermost position as that the spring 84 not only tends to hold the rod in its uppermost position but also tends to swing .the rod in a counterclockwise direction as viewed in Figs. 5, 6 and '7.

Since the solesupport for the bearing bracket 11 is constituted by the rod 8|, it will be apparent that under the influence of, the spring 84 the bearing bracket 11 will not only, be normally urged to its most elevated position, as shown in Fig. 1, but will also be urged'in a counterclockwise direction, as viewed in Fig. 5, thus tending to swing this bracket in adirection opposite to the arrow shown in Fig. 5, and thus holding the cutting wheel 1| in laterally spaced relation to the exterior of the tube T formed upon the mandrel .28. At certain stages in the operation of the tube winding portion of the machine, this cutting wheel 1| should be drawn inwardly toward the tube T until the cutting wheel 1| overlaps the cutting wheel 18 and this movement of the rotating cutting wheels 18 and 1|, relative to each other, will cause these two wheels to shear the tube T.

In view of the fact that during the time the cutting wheels 18, 1| are in overlapping relation to shear the tube T, the tube is moving downwardly along the mandrel, it is essential that the cutting wheels must also move downwardly along the mandrel at substantially the same rate at which the tube is being fed. This compound movement may be readily accomplished by providing a control cam 81 upon a stub shaft 88, the upper end of which is journaled in a bearing bracket 88 and the lower end of which is journaled ina bearing bracket 88, both brackets being secured to the front face o'fthe face plate 2. The stub shaft to .is provided with a gear 8| which meshes with a spur gear 82 secured to the drive shaft 55. The

ratio of gearing between the gears 8| and 82 is such that the cam 81 is given one complete rotation during the'forming and feeding of that much of the length of tube T as is desired to cut in order to form aflnished container. The cam '81 has a pair of cam surfaces 83 and 84 thereon (see Figs. 4 and 6); the cam surface 83 projecting laterally of the cam 81 to engage a pin 85 upon the outer end of a cra'nkarm 86 rigidly clamped as at 81 to the rod 8| so that whenever the cam tion shownin Figs. 6 and 7; that is,"in shearing or overlappingrelation with the cutting wheel 18.

At this point it should be observed that the lower end of the shaft 18 which carries the cutting wheel 1| is rotatably supported by one endof a link 88 secured to the shaft 8| as by means of a set-screw 88.

Immediately prior to the engagement of the 'crankarin 86 by the cam surface 83, the cam surface 84 engages aroller |88 (see Fig. 3) on a lever IN and moves this lever downwardly. The

lever IN is pivoted at |82 to the bearing bracket 88, the outer end ofthe lever |8| being connected as at I83 to the lower endofa link I84, the

' upper end of which connectsto an arm I85 rigidly clamped to the rod 8|;

From an inspection of Figs. 3 and 4 it will be observed that thedownward movement of the lever |8| under the influence of the cam surface 84, will cause the rod 8| to be drawn downwardly, carrying with it the .bearingbracket 11 which in turn carries the shafts "and 18' with the cutting wheels 18 and 1| downwardly with respect to the mandrel. The shape of the cam surface 84 is such that the downward movement of'the cutting wheels 18, 1| will.be substantially at the same speed as the lower end of the tube T moves downwardly as it is forined and fedupon the mandrel.

The combination of the movement of the cutto be lifted back to its extreme uppermost posi-,

tion, preparing the cutting wheels 18 and 1| for the next cutting operation. In this manner it will be apparent that predetermined lengths of the tube formed upon the mandrel 28 will be cut off from the tube at regular intervals, the length of the cut sections being determined entirely by the speed of rotation of the cam 81 relative to the rate at which the tube T is formed andfed along the mandrel. I 1

It will be apparent to those skilled in the-art that the amount .of actual time consumed in making a .cut and shearing off the predetermined length of the tube T will be relatively small as 'compared with the length of time required to wind up such length of tube.

From an inspection Jf Fig. 4, it will be observed thatthe position of the cutting wheel 18 shown in full lines represents the position of this wheel at the time a cut is to be made and the 'position of the cuttingv wheel 18, as shown in dotted lines of this figure, illustrates the total distance through which the cutting wheel wil move during the time of making one cut. 3

vIt will also be apparent that the machine thus far described will continuously form and feed the tube T along the length of the mandrel and such tube will be cut into, predetermined lengths by the cutting mechanism B to' continuously form a plurality-of cut lengths of tube ready to receive bottoms, napkins, or other accessories,

thereto. 1 a

It will also be observed-that the cutting discs 18, 1| will cut the tube bya shearing action wherein the entire wheel 18 will act as a rigid support filling the interior of the tube, while the cutting disc 1| is performing its shearing opting wheels 18 and" toward each other and their downward movement relative to the man-- I eration, and thus there will be no tendency to crush the tube or to tear the paper of which the tube is formed during the cutting operation.

Turret B The sections of tube now out to length are ready to receive the bottoms and should be conveyed out of the path of the advancing tube T constituting the next section so that we find it desirable to transport the cut section of tube laterally out of the path of the advancing tube T. We shall hereinafter refer to the cut section of tube as CT to distinguish the same from the length of tube T remaining on the mandrel in uncut condition.

By referring particularly to Figs. 1, 2, 3', 4 and 14, it will be noted that the turret C is constructed of a pair of spiders IIB, I each of which is provided with four openings 3. The openings H3 in the spiders are spaced at four equidistant points radially from the center of the spider to constitute openings into which may be seated the opposite ends of four tubular members constituting tubular casings H4, H5, H8 and Ill. The internal diameter of the tubular casings II4I I1 is slightly in excess of the external diameter of the cut section of tube CT so that the assembled turret constitutes four cylindrical chambers anyone of which may be aligned with the lower end of the mandrel to receive the descending end of the tube.

By referring particularly .to Figs. 1, 2, 3 and 4 it will be observed that the shaft II2-extends downwardly through a bore H8 in the bearing member 5? to extend through the centers of the spiders 5 ill, H i, the spaced spiders forming bearings which permit the turret to rotate upon the shaft H2 but which prevents any substantial lateral displacement thereof.- A boss H9 formed upon and extending below the lower spider Iii has a ball I28 received in its end, the material of the boss H9 being peened over about this ball so that the ball I26 may rest upon a die plate I24 (which will be more fully described hereinafter) to form a foot supporting the turret in upwardly spaced relation above the die plate I2I.

By referring particularly to Figs. 4 and '7 it will be observed that the upper spider Ilfl has either formed thereon, or rigidly secured thereto, a starwheel I22 which includes a plurality of arms I23 each disposed at 90 with relation to the other about the shaft 2 and each having'a slot 125 formed therein extending radially with respect to the shaft H2 and adapted to be engaged by a pin I25 on 9. Geneva driver I26. The

of a revolution to move the cut section of tube CT away from the advancing end of the tube T and to present the nexttubular casing in alignment with the advancing end of the tube C.

In the embodiment illustrated herein, it is assumed that the tubular casing H4 is ready to one rotation of the shaft 88 to make the cut the tubular casing Ill will be advanced to the next receive the cut section of tube CT so that upon position and the tubular casing I II will be placed immediately beneath the tube T ready to receive the next cut section.

tion of the Geneva drive wheel I26, we prefer to provide a spring catch 121 in the form of a spring-pressed ball which will seat in one of the slots I24.

It will be noted at this point that the tubular casings Ill-H1 are open at their bottoms so that the cut sections of tube CT received in any one of these will be free to fall therefrom unless supported by some other means. It will be noted, however, from an inspection of Figs. 1-8 and 14 that the die plate I2I has a shelf I28 secured thereto and extending forwardly thereof in a position to lie immediately below the lower end of the turret casing H5. That is, this plate is disposed immediately below. that one of the turret chambers which has received a cut section of tube and has moved to its next quarter-revolution position. It will also be observed from an inspection of Fig. 14 that that one of the turret casings 4 which is aligned to receive the cut section of tubeis disposed in spaced relation to the shelf I28 so that the cut section of tube would tend to fall through the casing IHl.

By properly timing the start of the movement of the turret C with the time of completion of the cut made by the cuttingmechanism'B, the cut section of tube will be moving to a position above the shelf I28 during the time it takes for the cut section of tube to fall through the turret casing H4 and thus the lower end of the cut section of tube will come to rest upon the shelf I 23 and be supported thereby.

By referring particularly to Fig. 4, it will be observed that the length of the cutsection of tube is represented by the distance between the lower face of the cutting disc Ill and the dotted line I29, the tube T advancing through the distance equal to the amount of vertical movement of the cutting wheel in during the cutting pperation so that at the end of the cutting operation the lower end of the cut tube section CT will be approximately at the dotted line indicated at I38. It will be observed that in this position the lower end of the cut section of tube has only partially passed through .the turret casing H 3 and his during the remainder of the movement of this tube section through the casing i I4 and the level indicated by the line l3! that the rotational movement of the turret is made.

It will therefore be noted that as soon as the section of tube CT is cut from the tube T it is transported to a position,90 away from the descending end of the tube '1'. The turret holds the cut tube section CT in this position until after the next section is cut from the tube and the turretis then again advanced through an arc of 90 to present the first cut section CT immediately above the die plate I2I. the cut tube CT is resting upon the shelf I28 it is allowed additional time for the drying of the adhesive which was employed to secure the outer and inner layers of paper strips together so that the out section of tube CT is substantially rigid and dry by the time it is delivered over the die plateJ2I.

During the time the cut tube section is held above the die plate I2I the bottom for the tube may be formed'and inserted therein and upon the next movement of the turret the cut section of tube will be delivered to a position immediately above the napkin inserting mechanism E to receive a napkin therein and finally, upon the next'quarter-turn movement of the turret C, the completed tube with its bottom and napkin will be brought back into a position of alignment During the time i Since the cut sections of tube are being carried by the turret C ina series of intermittent or stepby-step movements, a bottom may be formed and inserted in the lower end of the tube during one of the pauses made by the-tube as it is being con-- veyed by the turret. The mechanism for forming and inserting the bottom in the tube section CT is illustrated particularly in Figs. 2, 8 through 10, inclusive.

In the embodiment of the invention described herein, the bottom for each of the tubes is preferably formed by punching a'disc of paper from a strip of paper and then forming this disc into a cuplike member which'may be pressed into the lower end of the tube to a desired depth. These bottoms may be formed from a strip of bottom stock BS which is preferably selected to be of such weight as to hold its shape after it has been formed into a cuplike bottom member. The bottom stock is illustrated imFig. 2 as being supplied from a reel I46 supported in any suitable I manner as indicated inFig. 2 upon the upright 33, and from which the strip BS may be drawn through an oiling mechanism I which consists I46a, accommodating the paper feeding 'mechanism.) The feed roller I43 is normally springpressed toward the roller I44 by means-of mounting the roller I43 upon the lever arm I41 pivoted at I48 upon the bearing member I45 and urging-this lever toward the bearing plate I45 by means of a spring I49. The feed roller I44 is rigidly secured to a drive sprocket I56 driven by means of a chain II from a cam shaft I52 (see Figs. 1 and 2). The feed roller I44 also has a gear I53 mounted thereon and continuously in mesh with a gear I54 on the feed roller I43, so that both of these rollers will be driven at the same speed to continuously draw the bottom stock BS from the roller and feed the same "toward the bottoming mechanism.

The bottom stock BS proceeds from the. con-' tinuous feed rollers I43, I44 through-a pair of intermittently rotated feed rollers I55, I56 also mounted upon the bearing plate I45, a loop I51.

being formed in the strip BS between the continuously operating feed rollers I43, I44 and the intermittent rollers I55, I56.

The feed roller I56 has secured thereto a gear I58 meshed with a gear wheel I59, the outer face of which is provided with a plurality of radially extending flanges I66 adapted to be engaged by a pin I 6| on a Geneva driver arm I62 secured directly to the sprocket I56 employed to drive the feed rollers I43, I44 so that after each revolution of the drive sprocket I56 the gear wheel I59 will be driven through one-quarter of a revolution to thus cause the intermittent feed rollers I55, I56 to intermittently feed a predetermined length of the bottom stock across and immediately belowthe die plate I2I. The feed roller I55 preferably has a gear I63 thereon meshed continuously with the gear I58 so that this roller, like .roller I56, is positively driven and the roller I55 may be mounted upon a lever I64 pivoted at I65 on the rail I46 to be spring-pressed toward thev roller I56 by means of a spring I66.

The bottom stock BS, intermittently moved forwardly by the intermittent drive I 55, .I 56 passes through a slot. I61 formed between the lower surface of the dieplate HI and a cylinder I68.

'Withinthe cylinder. I66 8. cutting die I69 is reciprocably mounted to be moved vertically toward the die plate I 2| to cut a paper disc from the bottom stock BS each time the bottom BS is moved forwardly. The die plate I 2I is provided with a die surface I16 formed on thelower surface.

thereof to constitute the complementary die surface against which the die plunger I69 may operate to assist in the shearing or cutting of paper disc from bottom stock BS.

The die plunger I 69 is reciprocated vertically by means of a cam I1I secured to thecam shaft I52, and rotated through one revolution upon each revolution of the cam shaft I52. A lever I12 pivoted at I13 upon the rail I46, has'its lower end provided with a roller I14 which bears upon and rides upon the surface of the cam I1I, the lever I12 being. provided with an up standing foot I15 adapted to rest immediately below and in engagement with a fork I16 (also pivoted at I13) the upper surface of the fork rests immediately againstthe lower end of the die plunger I69. Thus upon each rotation of the cam shaft I 52 the die plunger I69 will be raised to the position shown in Fig. 9 and then will be'permitted to retract back to its normal rest position, as shown in Fig. 8. The uppermost position assumed by the plunger I69 may be adjusted, if desired, by adjusting the length of the footpiece I15, which is illustrated as comprising a threaded member which is threaded into a shelf I11. formed upon the lever I12 and may be held in the desired adjusted position by means of a lock-nut I18.

The bottom disc BD formed by the operation of the die plunger I69, is now ready to be formed into the cuplike bottom-member ready for insertion into the bottom end of the cut tube section CT. As shown in Figs. 8 through 10 inelusive, the die plunger I69 has a central bore I19 within which reciprocates a forming plunger I86, the upper end of this plunger I86 being preferably slightly rounded at its peripheral edge to constitute a smooth surface for pressing the shaft I52, upon which rides a roller I83. The

roller I83 is carried by a pin I84 the outer ends of which bear a "pair of links I85; I86, the upper ends of which engage in curved recesses I81 at the lower end of the forming plunger I86. A

In order to prevent forward and rearward displacement of the links I85, I86 as they are lifted and lowered by the cam I82, a secondary link I 88 may be provided, engaging the pin I84 and having its rear end pivoted to the rail I46 as indicated at I89.

From an inspection of Fig. 8, it will be observed that the relative positions of and the relative curvatures of the cam surfaces of the two cams III and I82 is such that the first operation which takes place upon the rotation of the cam shaft I52 is to lift the die plunger I69 to punch the disc from the strip of bottom stock and after the shaft has completed approximately 60 more of its rotation, the forming plunger I80 will be lifted to start the forming operation to form the disc into cuplike bottom members.

It will be noted however that during the initial upward movement of the forming plunger I the die plunger I89 will be holding the annular portions of the surface of the disc Bl) tightly against the shoulder I90 between the forming die I8I and the die I so as to evenly clamp'the disc about its periphery during the start of the forming operation and thus will insure that the. upward movement of the forming plunger I80 will produce a cup-like form in the bottom disc substantially as shown in Fig. 10. As hereinbefore noted, the bottom stock BS has been given a thin coating of oil which constitutes not only a lubricant for the disc BD as it is pressed through the forming die IBI, but also assists in softening the fibers of the paper stock to some extent to prevent undue tearing or cutting thereof, as the disc ED is formed into its cuplike shape.

It will also be noted from an inspection of Figs. 8 and 10 that the forming plunger I80 has a considerably greater length of stroke than the die plunger I69 so as to permit the forming plunger to pass upwardly through the forming die I85 and to enter a considerable distance within the lower end of the cut section of tube CT. The relative positions of the forming plunger. the die plunger and the cupped disc BD at this, time is illustrated particularly in Fig. 10.

As hereinbefore explained, it is desirable that the bottom formed by the disc EU should be pressed upwardly into the cut section of. tube CT to a position a considerable distance above the lower end of the tube CT so as to provide a space or chamber in the lower portion of the tube for the insertion of a napkin or other accessory. For the purposeof pressing the bottom disc BB up to its inwardly spaced position, the forming plunger I80 is provided with a central bore ISI through which extends a stem I92 carrying upon I its upper end an elongated carrier plunger I93,

nesting in theforming plunger I00 in an enlargement IQ! of the bore iiii. The lower portion of the stem I92 is guided in a suitable bushing by means of a bolt I97 and a link I90 to a lever I99 which is pivotedat m to the flange m and carries intermediate its ends a roller III secured to the lever I09 by means of a pin 202. The roller 20I projects into and operates within a cam slot 202 formed upon the face of a, earn 204 also rigidly secured to thewam shaft I52 so that as the cam shaft completes one revolution the carrier plunger I03 will be movedupwardly and then downwardly.' l

By referring to Fig. 10, it will be observed that after the disc BD has been formed in a cupliie, bottom any further upward movement of the carrier I9 3 will slide this cuplike bottom member upwardly into the tube section CT to the position indicated in dotted linesat 205.. As the bottom disc ED is forced up into the tube CI it will tend to lift the tube. This upward thrust, however, is resisted by disposing a plate I2Ia. immediately above the turret C so as to engage the upper end of the tube and constitute an abutment preventing any appreciable upward movement of the tube CT.

As was hereinbefore described, the bottom is held in its desired position within the tube section CT by means of a suitable adhesive, perhaps the most desirable being wax and such adhesive or wax may be applied both to the bottom disc BD and to an annular space around the interior walls of the tube CT by means of a waxing nozzle 206. It will be noted from an inspection of Figs. 1, 8 and 10 that the waxing nozzle is carried upon the lower end of a tubular nipple 201 through which wax may be supplied to the nozzle, the point of egress of the wax from the nozzle being through a wax gate 208 formed in and passing through the lower face of the nozzle 206 and adapted to be closed by a ball valve 209 normally pressed by a spring 2! which bears between a pin 2I I and the upper surface of the ball valve 209 to normally urgethe ball valve into seating, or valve-closing,

$. The cylinder 2 I2 is illustrated as being sup-- ported upon a bracket 295, secured to the front face of the face plate 2 and is provided at both of its ends with a stumng box 2&5 and M1, respectively, so that the nipple 20? may reciprocate through the cylinder 252 without danger of leakage of theiwax between the cylinder and the nipple. The upper end of the nipple 201i is connectedas by 8 lug 2i! to the upper end of a gear rack M9. The upper end of the nipple 207 is locked in place on the lug 2 I 8 by means of a locknut 220. From an inspection of Figs. 1 and 2 it will be observed that the gear rack 2 i9 is meshed with a gear 22I rigidly secured to a stub shaft 222 rotatably mounted in the gearing bracket 215, the

shaft 222 having a second gear 223 thereon meshed with a gear rack 228 formed uponthe upper end of a rod 225 pivotally connected at 225 to the outer end of a link 221. the link 22! is pivoted at 228 to the left-hand The inner end of v hearing bracket 230 which constitutes the lefthand bearing for the cam shaft I52.

The link 22'! carries a roller 229 which rides upon a cm 230 also carried by the cam shaft I52 so that as the cam shaft I52 is rotated through one complete revolution the cam230 will permit the rod 225 to first be moved downwardly and then upwardly to produce first a downward stroke and then an upward stroke on the nipple 20; and

the wax nozzle 200. In order to insure a positive downward movement of the rod 225 we prefer to provide a tension springr23l connected at 226 to the link 221, the opposite end of the spring 221 being connectedat 222 to some stationary part of the frame of the machine. It may be desirable to provide a guide for the upper end of the nipple 201 independent of the stufling box 2H5 and we have illustrated the same as comprising a rod 233 connected to the lug 2" and extending upwardly through thebearing bracket 22.

movement of thenozzie 200 through its entire The relative positions and surfaces of the cams 200 and the cam slot 200 (which controls the movements of the carrier plunger I) is such that when the carrier plunger is in the position shown in Fig. (that is just at the completion of the forming operation performed upon the bottom disc BD) the waxing nozzle 200 isin its lowermost position. In this position the waxing nozzle 200 is almost incontact with the upper surface of the forming disc BD and a pin 200 passing through the bottom face of the nozzle 200 is. brought into engagement with the upper surface of the forming disc BD. a

The foregoing operation will cause the pin 204 to be moved inwardly of the waxing nozzle 200 to engage and lift the ball valve-200 from its seat in the wax gate 200, allowing wax ,whichhas accumulated in the nozzle to pass downwardly. through the gate. Since it is desired to apply the adhesive not only to the forming disc BD but also to the interior wall of the tube section CT, we

' prefer to form 'the wax exits of the nozzle 200 as It should be noted at this point that the wax Y being liquid it forms a substantial lubricant, facilitating the movements of the disc BD upwardly in the tube CT, in the dotted line position shown in Fig. 10 and passes out about the time the disc will arrive at the dotted line position and commences to cool so as to form an adhesive holding the disc in this position.

It should also be observed that the spraying of the wax occurring at the time the nozzle 200 is disposed almost in contact with the disc Bl), sprays a quantity of the wax over the upper surface of the disc BD and a film of wax is thereby formed both upon the upper surface of the disc BD, rendering the same moistureproof and also injecting a considerable quantity of such wax at the annular space formed by the curved Junction between the peripheral flange of the disc BD and its upper face.

It should also be noted that the roller 220 merely rides upon the surface of the cam 230 and the relative location of the cam surface 200 and thecam surface 200 is such that when the carrier plunger I00 rises above the forming plunger I00 it will bring the disc BD into contact'with the valve of the waxing nozzle .200 and further upward movement of the carrier plunger I03 will, as it presses the disc BD upwardly into place,

lift the waxing nozzle 200 upwardly with it to thus insure thatthe wax will be sprayed freely throughout this last part of the upward movement of the disc BD to its dotted line position as shown in Fig. 10. Thus causes the distribution of the wax throughout this complete area. When the waxing nozzle 200 is lif ted by the carrier plunger it will merely lift the roller 220 0B of its cam 230 and by this construction careful timing of the-cam. 230'with the cam surface 204 is obviated. When the plunger I03 reaches the uppermost limit of its stroke, this plunger will start to descend and at this time the cam 200 will, in its rotation, continue the upward limit of stroke. The carrier plunger I00 in descending will be retracted into the forming plunger I 00 until the lower end of the plunger I00 engages the shoulder formed between the enlargement" I04 and theremaining portions of the bore HI, and as the forming plunger I00 is drawn further downwardly; it will carry the forming plunger ill to its lowermost position, as shown in Fig.8.

At this point it should be observed that the length of the slot' 2 and the nipple 201 should be such that during one stroke of the nipple 201 through the cylinder 2I2 only such quantity of wax will be'admitted to the nipple 2lI-200 asv will be permitted to be ejected by the nozzle 200 during that same strokeof the nipple 201. In this way the wax which is delivered to the nozzle 200 may be kept'relatively hot until its ejection, sinceprior to the start of the downward stroke of the nipple 201 the wax is contained within the cylinder H2 and may be heated therein to any desired temperature by means of a heating coil 200 wrapped around the cylinder 2 and electrically insulated therefrom by any suitable means well known in the art. Also the wax, beingdelivered. through the small tube-or pipe 2| 0 from the wax pct 40, requires that the pipe 2" should also be kept hot and this may be accomplished by supplying a heating element for the pipe 2", or by connecting the pipe 2|; itself in anelectric circuit wherein these pipes constitute a conductor for electric current.

It will be understood that all of the foregoing operations of the die plunger I00, the forming plunger I10, the carrier plunger I00, and the waxing nozzle 206, will have occurred during one pause between successive steps of movement of the turret C. Itwill also be observed that the cutting of the disc BD, the forming thereof, and

the-placing thereof within the tube CT will all occur during the pause in the intermittent feeding movement of the bottom stock B8 by the intermittently operated feed rollers lib-I00, so that after the bottom BD has been placed within the tubing section CT and the various plungers have been withdrawn therefrom, the turret C is free to be moved to its next stop while duringsuch movement of the turret theintermittent feed rollers I50, I08 are operated to feed a new length of bottom stock into the space below the forming operation upon the next tube, carried in the next chamber of the turret C. 7

It will therefore be observed that'at this stage of operation of the machine, the tube section CT has been wound, cut-oil, delivered to the bottoming mechanism, and has received a bottom there'- Napkin folding and inserting mechanism The tube having its bottom spaced inwardly from the lower end thereof, is now ready to receive the napkin or other accessory to be inserted. in the lower chamber of the tube CT. In order to facilitate an understanding of the napkin innism should also be considered at this time.

In the embodiment of the machine'i'llustrated herein, the accessory which is to be inserted into the bottom chamber of the tube CT is a paper napkin, which is particularly desirable when the container formed by our machine is to be used in connection with ice cream or similar liquid,

or semi-liquid, .products.- The napkin may be die plate i2l, ready for a subsequent bottomserting mechanism, the napkin foldingmecha-' formed and folded in any suitable manner, and supplied to the machine for insertion intothe bottom chamber of the tube CT, though'we prefer to continuously and automatically fold such napkin from a'roll of paper napkin stock, the entire folding operations being performed by our machine. I

Referring particularly to Figs. 1, 2, and 3, it will be observed that a roll 256 of paper napkin stock 1. NS may be riotatably'mounted upon the frame of the machine, as, for example, mounting such roll upon arod 25! supported in a pair of brackets 252, 256 secured, respectively, to the uprights 9 and II constituting a part of the'frame of the 1 machine. From the roll 250 the napkin stock convolutions.

essentially in a base plate 255, the rear end of NS may be drawn upwardly over a guide plate 254 to a fanning device H, which will fold the strip of napkin stock along a plurality of longitudinal lines to fold .the same into a plurality of The fanning device H consists which carries a pair of vertical supports 256, 251, between which extends a bowed'guide'wire 256 so that as the napkin stock NS is drawn thereoverthe side edges of the napkin stock will tend closely spaced relation to each other so that as the napkin stock- NS is drawn over these blades it is formedthereover in a series of convolutions, the number of which is determined by the number of blades 259, 26l, and as the napkin stock progresses across these blades, these convolutions are brought closer and closer together until when the napkin stock passes beyond the blade block' 264 the entire width of the napkin stock NS has been folded, or convoluted into a fan-shaped form, the total width of which is but a fraction of the total width of the napkin stock.

To assist in the folding of the napkin stock over the blades 259-262, we provide a second set 'of'blades 265, 266, 261, 266 and 259, the rear ends of which are all supported upon a blade strip 216 in equidistantly spaced relation to each other. The outside blades 265-269 preferably extend rearwardly to engage a pivot rod 21! supported upon a pair of uprights 212 and 216 rising from the plate 255 to permit the upper set of blades 265-469 to be elevated to the dotted line position shown in Fig. 16 during the threading of the napkin stock across the fanning device H.

' It will be observed from an inspection of Figs. 15 and 17 that the spacing of the blades in the upper set ISL-2661s substantially equal to the spacing of the blades in the lower set (259-262) from each other so that when the upper set of blades is folded down into the full line position shown in Figs. 15, 16 and 17 one of the lower blades will enter into the space between the two.

adjacent upper blades and will be disposed substantially centrally of said space.-

The forward ends of the upper set of blades 265269 are supported in an upper blade block 214, which is disposed immediately above the blade block 264, and the blades in the upper set gradually approach each other in the same manner as was described with reference to the blades in the lower set so as to draw the convolutions tward each other, as was described with reference to the lower blades. ing of the paper stock NS through the fanning de- Thus by the mere drawvice H, the napkin stock is. folded along longitudinal lines into the shape described. The spacing of the blade blocks 264 and 214 from each other determines the width of each of the convolutions into which the napkin stock is folded and this width may be varied by changing the spacing between these two blade blocks by means of an adjusting screw 215 on the blade block 214, which projects downwardly therethrough, in such manner that the head 216 thereof engages and rests upon the blade block 264. The effective length of the adjusting screw 215 may be varied by a1- tering the position of a locknut 211 and a wingnut 216 as will'be apparent from an inspection of Fig. 18.

The fanned or convoluted napkin stock NS now .passes beyond the blade blocks 264, 214 through a creaser which may consist of a pair of leaf spring members 219, 266, one disposed on each side of the folded napkin stock, and arranged to bear toward each other and engage the napkin stock between them. The leaf spring 219 may be supported upon the plate 255 by meansof passing the same about a pair of upright posts 26I, 262, as indicated in Fig. 15, while a similar support of the leaf spring 266 on posts 266 and 264 may be employed.

When-the convoluted napkin stock NS leavesthe creaser 219, 266 it enters a channel-shaped guide 265 which guides this stock toward the face plate 2 of the machine, producing a right angle twist therein as illustrated particularly in Figs. 2 and 3.

The motive power for drawing the napkin stock from its roll 256 is illustrated particularly in Figs. 3 and 11, as comprising a pair of feed rollers 266 and 261 between which the napkin stock NS is gripped and fed. The roller 261 is mounted upon a shaft 266 which carries a sprocket 266 arranged to be driven by means of a chain 296 from a sprocket 291 mounted upon the extreme right-hand end of the cam shaft I52 as viewed inFlg. 1. e

The roller 261 also has a gear 292 formed thereon constantly meshed with a gear 266 on the roller 266 so that each of these rollers is positively driven by power transmitted through the cam shaft I52 and coordinated in timed relation with the movements of the cam shaft I52 and the cams controlled and operated thereby.

By referring particularly to Fig. 11 it will be observed that the napkin stock feed rollers 266 and 261 are both journaled in a bearing member 264 secured to the face plate 2 and projecting through a slot 265 formed through the face plate the extending end of the napkin stock NS is fedby the rollers 266, 261. The vertical extent of the napkin hopper 291 is slightly in excess of the desired length of a section of the napkin stock necessary to form a napkin when the same is cut from the supply of napkin stock. The cutting knife 296 is pivoted at 296 upon a shearing block 269, secured to the face plate 2 (see Figs. 11 and The knife 296 is normally disposed in the position shown in full lines in Figs. 11 and 13 and is adapted to swing from this position first rearwardly to the position indicated by the center .shoulder 32! before the spring 320 can bring this line 300, and then forwardly to the position indicated by the center line 30l during one cutting operation.

It will be noted that as the knife moves to the position shown at 30!, it will sever the extending end of the napkin stock from the remainder of the stock.

The-knife 296 is operated through its series of positions by means of an oscillatinglever 302 pivoted at 303 upon a bracket 304 secured to the face plate 2. From an inspection of Fig, 11 it will be observed that the lever 302 projects upwardly in the path of movement of a crankarm 305 attached to and operating with the shaft 288 upon which the feed roller 28'! is mounted so that as the feed roller-28! is moved in the direction of the arrow appearing thereon in Fig. 11,

' the lever 302 will first be drawnrearwardly and then as the pin 306 on the crankarm 305 passes the upper end of thelever 302, the lever will be swung forwardly toward the base plate 2 under the influence of a spring 301.

Thespring surrounds a bar 308 secured to the rear face of the face plate 2, and having an elongated slot 309 therein through which the lever 302 projects, one end of the spring 30! abutting a washer 3!0 engaging the rear surface of the lever 302, while the opposite end of the'spring 30'! engages a washer 3|! at the outermost end of the bar 308.

. the knife 296 by means of a link 3l2 and the spring 30'! is selected of such strength and characteristics that when the lever 302 has been reface of the face plate 2. It will thus be apparent that when the knife 296 is swung to its forwardmost position 30l the tailpiece 3l3 will engage the spring 3M to impart a slight rebound to the knife 296. 1

Since the knife is actuated by a snap action it.

is necessary that some means be provided to prevent a secondary cutting operation of the knife after it has made one cut, and for this purpose we prefer to provide a holding mechanism which will catch the knife 296 upon its rebound and hold the same until the next retraction of the lever 302 by the crankarm 305. This holding mechanism may comprise a lockbar 3!! pivoted at 318 upon the bar 300' and havingafnotch 3l3 in one side thereof, adapted to bear against that upper portion of the lever 302 which projects above the bar 308, The rearportion of the notch 3!!! is beveled slightly so as to offer no resistance to the rearward movement of the lever 302, even though the lockbar 3!! isnormally spring pressed by means of aspring 320 toward an engaging relation with the lever 302. The front a portion of the notch 3l3 is provided with a right- The lever 302 is connected to shoulder into engagement therewith, but upon the retraction or rebound of the knife 233 under the influence of the spring 3, the lock lever 3i! will now be in a position toengage the lever 302 in the notch 3H and prevent a second forward movement of the knife 235.

The cut length of napkin stock should now be folded laterally into a-reiatively small compass so that it may be inserted in the hollow chamber in the lower end of the tube section CT and this is accomplished by means of the napkin folding and inserting 'mechanlsm including a pair of lateral folding blades 330 and 33! secured to a Fig. 11) are similarly interconnected by means of a crossbar 333 to constitute a guide frame along which the cross head 333 may reciprocate in a horizontal direction. It will be noted also from an inspection of Fig. 11, that the napkin hopper 23'! has a forwardly extending portion 340 which extends through the face plate 2 to a position disposed below the turret C and preferably aligned with that one of the tubular cas- -ings of the turret which has just been moved from the bottom inserting position of the machine,

The forward end of the extending portion 343 of the napkin trough 29! is provided with a slot 3 into which may pass a secondary holding plate 342 carried upon a cross head 343 mounted upon'and reciprocating upon the guide rods 334 and 335.

In the operation of laterally folding the napkin, the cross heads 333 and 343 are drawn toward each other until the blades 330, 33! are brought into overlapping relation with the secondary blade 342, as shown particularly in Fig. 12, to cause the blades v330, 33! to engage the napkin, press the same forwardly in the extension 340 of the nakpin hopper 29! and to cause the blade 342 to engage the napkin intermediate the blades 330, 33! to fold the center of the napkin back in between these blades. The reciprocation of the folding blades 330, 33! is accomplished by se curing the cross head. 333 to a 'link 344 which I is in turn connected to a lever 345 pivoted upon the stub shaft 200 in a bearing member 341a mounted upon the front face of the face plate 2.

The lever 345 carries'a' roller 34! which engages in a cam slot 348 in a .cam 349 (this cam also being carried upon and rigid with the cam shaft I52) The shape of the cam slot.348 and its relation to the remaining cams on the shaft I52 "is such that during the time when the cam mechanism is operating to punch and form the bottoms gear 35l is a second gear 353 which meshes with a gear rack 354 secured to the cross head 333. Thus as the cross head 333 moves forwardly, the cross head 343 will be brought rearwardly until the folding blades 33!), 33l and 342 assume the position shown in Fig. 12. The folding blades 336, 33l and 342, are then retracted to their normal positions, as shown in Fig. 11, leaving the folded cut section of the napkin stock NS in the position shown in Fig. 12, ready to be pressed between the interior chamber formed in the lower end of the tube CT.

The insertion of the napkin NS in the tube CT is now accomplished by a napkin inserting,

plunger 355 mounted for vertical reciprocation in a bracket 356 secured to the front face of the face plate 2. The napkin inserting plunger 355 has a lug 351 secured thereto and coupled by means of a link 358 to a lever 353 pivoted upon the stub shaft 266and having a roller 366 operating in a cam slot 36! upon a cam 362, the cam 362 being mounted upon the same cam shaft I52 upon which the remaining cams are mounted.

The shape of the cam slot 26l and its relation to the remaining cams, is such that during the latter portions of the time consumed by the forming and insertion of the bottom BD in the tube CT, the napkin inserting plunger 355' is moved upwardly to engage the folded napkin NS (in the position shown in Fig. 12) and to move this napkin upwardly into the bottom of the tube CT to the dotted line position thereof shown in Fig. 12. It should be noted from an inspec tion of Figs. 11 and 12 that the extension 340 of'the napkin hopper 231 is provided with a pair of aligned vertical openings 363 and 364 through which the plunger 355 operates, permitting the napkin NS to be pushed up through the slot 363 and into the bottom of the tube CT.

As hereinbefore described, in connection with the operation of the turret C, immediately after the insertion of the napkin in the bottom of the tube CT, the next possible operation of the turret C will carry the tube CT from the napkin inserting position in alignment with the now descending end of the tube T on the mandrel, and at this point the completed tube CT, with its napkin, will fall out of the turret, ready for filling.

Glue pot F By referring particularly to Fig. 20, it will be observed that we have provided a glue pot particularly adapted for operation with our machine, this glue pot consisting essentially of a cylindrical pan or container 365 having a cover 366 thereon from which is suspended a roller 361 at least the major portion thereof being immersed in the glue pan 365. The upper surface of the top 366 is provided with a vertically extending bearing member 361' in which is journaled a, shaft 364 carrying a glue-applying roller 363, this roller preferably being provided with a plurality of annular peripheral slots 313 adapted to hold a quantity of glue upon the periphery of the roller. The roller 363 bears in contacting relation upon the roller 361 so that glue picked up by the roller 361 is transferred to the roller 363. It will also a be observed from an inspection of Figs. 2 and 20 that the paper strip S--2 is passed directly over the upper surface of the roller 369 and is guided into positive contact therewith by means of a,

315 extending from the top 366 of the'glue pot.

- are delivered to the turret.

By this construction the entire frame 313 may be lifted to assist in the threading of the paper strip -2 over the glue-applying roller 369. If desired a scraper 316 may be provided, this being illustrated as an inverted U-shaped strip of metal carried by the top 366 of the glue pot and disposed immediately above a drip opening 311 in the glue pot top.

As the excess glue is scraped. from the underneath surface of the strip 5-2, it will fall through the drip hole 311 and back'into the glue pot. The glue pot may be provided with any suitable heating mechanism to keep the glue warm and at the desired consistency and viscosity. The wax pot G is illustrated particularly in Figs. 2, 3 and 19 as comprising a substantially rectangular pan 318 having a cover 313. An extension 386 at one of the side walls of the pan 318 provides a sump 38I communicating with the interior of the pan through which melted wax within-the pan may pass out thereof. Suitable heating mechanism may be applied to the wax pot to maintain the wax therein at a predetermined temperature.

Rotatably mounted in the sump 31 is a wax-applying roller 362, over which the paper strip S-l passes, said strip being guided into contacting relation therewith by a pair of guide rollers 383 and 384.

If desired, the scraper 336 illustrated as being an inverted U-shaped strip of metal may be provided to scrape the excess w ax from the strip S--l and return the same to the sump 331.

Summary delivered to napkin or other accessory inserting device which will insert a napkin or other accessory into the bottom end of the container and the finished container, with its accessory, will be delivered ready for the reception of the contents. It should be noted that the cam shaft I52 which controls the bottoming, the napkin folding and inserting operations, is preferably connected to its source of driving power through the agency of a clutch 385, which may be controlled by means of a clutch handle 386, the clutch 385 being preferably a pin type clutch, one element of which is connected directly to the cam shaft I52, while the other element is secured to a hub 331 engaged by a cooperating bevel gear 383 on the lower end of the drive shaft 55. v

Thus during the threading operations of the machine which may necessitate the operation of the winding roller 2| to start the winding of the tube T, the bottoming and napkin folding and inserting mechanisms may be rendered idle until the completion of the'threadingoperations and insure that these mechanisms will be operated only when properlyformed cut sections of tube While we have shown and described the preferredembodiment of our invention, we do not wish to be limited to any of the details of construction shown herein, except as defined in the appended claims.
